Ucwaningo lwase-Canada oluphenya ukusebenza kwesikhathi eside kwe-polystyrene enwetshiwe (EPS) lapho kuthintana nomhlabathi kwenze abakhiqizi be-EPS eNyakatho Melika nase-Canada basho ukuthi ukufakwa kufanele kusetshenziswe phansi, okufana nokusebenza kwe-polystyrene ekhishwe (XPS). ).
Ngokulandelayo, ngokusekelwe ebufakazini bokwehluleka kwe-shingle, ucwaningo oluxhaswe yimboni lubonise ukuthi ukusebenza kwe-XPS kuzinhlelo zokusebenza zomhlaba wangempela akufani nokuhlolwa kwaselabhorethri, okwenza i-EPS ibe yinto ephambili. Nakuba imboni ye-XPS iyiphikile le miphumela ngocwaningo lwayo, kuyathakazelisa ukuthi abakhiqizi be-XPS basuse ukugxila kwabo ku-hygroscopicity ephansi ebonwa ekucwilisweni kwaselabhorethri kanye nezimo zomoya eziswakeme baya endaweni yokusabalalisa umswakama we-XPS.
Ukwehluleka okuningi kwe-XPS kungenxa yezimo ezinzima zokufakwa kwe-shingle kanye nokusetshenziswa kwezinto ezihlanganiswa nezinga eliphansi lolwelwesi lokuvikela amanzi. Kunobufakazi bokuthi i-XPS ingcono uma kungekho ukugeleza kwamanzi ngamabomu eduze nangaphansi kwe-insulation, okunikeza ukumelana nomswakama okwengeziwe lapho uthintana nomhlabathi.
Ukufakwa kwepherimitha ye-EPS kuvamile ukufakwa ngokugcwaliswa kwangemuva kokukhipha amanzi, i-polyethylene yokuvikela igwebu, namapayipi okukhipha amanzi ngaphansi kokufakwa. Kodwa-ke, i-XPS ifakwa kuphela kusetshenziswa ulwelwesi lwe-polyethylene.
Ukwakheka kwe-EPS kanye nokufakwa kwe-XPS kushintshile ngokuhamba kwesikhathi, isibonelo, ama-ejenti afuthayo azo zombili izinto ashintshile. ENyakatho Melika naseCanada, i-XPS okwamanje ikhiqizwa ngaphandle kwama-ozone aqeda ukuvunguza, kodwa akunjalo kwenye indawo. Eminye imikhiqizo ye-XPS engeniswe eNew Zealand kubonakala sengathi yenziwe ngokusika izinto ezixegayo kunokuyikhipha ebukhulu besikhumba. I-cuticle eshidini le-XPS ibambezela ukuguga futhi inegalelo elikhulu ekugcineni umswakama.
I-BRANZ ihlole umkhiqizo we-XPS onokuhambisa okushisayo okungu-0.036 W/mK. Ngokuphambene, i-conductivity ye-polystyrene foam egcwele i-carbon iphansi kakhulu kunaleli nani. Iningi lama-styrofoam akhiqizwa eNew Zealand aqukethe izinto ezigaywe kabusha futhi kwesinye isikhathi angaba nesakhiwo esinezimbotshana.
Ukuvumela umswakama ukuthi usakazeke emhlabathini, kuhle ukuthi igwebu akufanele limbozwe ngokuphelele umgoqo ongenamanzi. Ebusika, noma imuphi umswakama ongaphansi kodonga uzophoqeleka ukuba ungene ku-insulation ye-perimeter, ngakho-ke kungcono ukusebenzisa umgoqo we-steam ngaphandle kwe-insulation. Uma lokhu kungenakwenzeka, igwebu kufanele lingene emhlabathini, lishiye kuphela ungqimba oluvikelayo olungenakuvinjelwa lwezingxenye ezingaphezulu komhlaba.
Njengomthetho ojwayelekile, okuqukethwe kwamanzi kwesisekelo akufanele kube phezulu kakhulu, ngakho-ke ingozi eyinhloko ekubuyiseleni kabusha ivela kumphumela we-capillary lapho amanzi engena phakathi kwe-insulation kanye nokhonkolo. Lokhu kungagwenywa ngokusebenzisa ikhefu le-capillary (isb. i-butyl tape) emaphethelweni angaphansi kwesivikelo.
Bhalisa ukuze uthole zonke izindaba, ukubuyekezwa, izinsiza, ukubuyekezwa kanye nemibono mayelana nezakhiwo nokuklama ngqo ebhokisini lakho lokungenayo.
